|
摘要
大港油区的段六拨油田是典型的低渗透油藏,储层平均渗透率31.3×10-3μm2,平均孔隙度15.9%,为中孔低渗油藏。为了解决段六拨油田开发中存在的主要问题,改善开发效果,提高采收率,本次研究以油气藏开发理论为指导,采用确定性建模与随机建模相结合的油藏建模技术,利用质量控制和网格粗化等,最大限度的应用计算机手段,进行油气藏内部结构精细解剖,揭示油气分布规律,建立能描述油气分布状况和流动特征的地质的、岩石物理的、成岩的、构造的、流动的及工程的油藏精细模型。
从井网、层系适应性、开发方式和工艺适应性等方面展开油藏工程综合研究,重新精细认识构造和储层,有效解决在多年开采中因层间矛盾加剧导致含水上升加快等突出问题。在沉积微相和储层认识的基础上进行数值模拟研究,分析剩余油分布主控因素,找出可采储量平面分布规律,进而对开发效果综合评价,扩边部署产能井拓宽储量接替区带。同时开展单砂层合理井网密度和产能潜力综合评价研究,编制新老井相结合的综合调整方案,为段六拨油田综合治理、提高最终采收率提供科学依据。
Duanliubo oilfield of Dagang area is typical of low permeability reservoir. The average permeability of reservoir is 31.3×10-3μm2,and the average porosity is 15.9%, which belong to the medium porosity and low permeability reservoir. In order to resolve the main problems existing in the development of Duanliubo oilfield, improve development results, and enhance oil recovery, in this paper, inner structures of reservoirs are anatomized, oil-gas distribution patterns are reveled, and reservoir fine geological, petrophysical, diagenetic, tectonic, flowing, and engineering models which can describe oil-gas distribution status and flow characteristic are built by taking reservoir development theories as a guide, using deterministic and stochastic model-building techniques,utilizing quality controlling and grid coarsening,and maximally applying computer tools.
Comprehensive researches of reservoir engineering are carried out from well network, layers series adaptability, develop mode, technique adaptability etc.Re-recognize structure and reservoir finely,and to resolve the serious problems of water cut icreasing and accelerating ect which caused by interlayer interference because of exploiting for years efficiently.In order to widen replacement of reserves to deploy production well,based on sedimentary micro-facies and reservoir,studies on reservoir numerical simulation to analysis main control factors of remaining oil and find out recoverable reserves distribution patterns of plane and then comprehensive evaluation of development results are conducted.At the same time comprehensive evaluation researches of single sand layers in reasonable well spacing density and production of potential are performed, integrated adjustment scheme of combination of new wells and old wells are complied in order to make a scientific basis to management and enhance ultimate recovery of Duanliubo oilfield.
